Besides structural steel what would be some common loads for 65 ft.
steam era gons?
Would structural steel be I beams and the like?
Were electrical transmission towers preassembled (drilled and assembled
into subsections)? They would make interesting gon loads.
Years ago I met with a man who worked on a railroad during the summer
in the early '50s. He told me some kind of metal was shipped in bales
in these long gons (not scrap).
